COMPUTER PROJECT:

COMPUTER PROJECT LATEST TECHNOLOGIES + NEW INVENTIONS By:- Manish (student)

SMALLEST LASER IN THE WORLD:

SMALLEST LASER IN THE WORLD The latest invention of American researchers is the laser that claims to be the smallest in the world. They managed to develop the laser by squeezing light into a space that is even tinier than a protein molecule. Their latest invention could be a significant breakthrough in the field of optical technology , making one step closer to nanolasers , which can be used to investigate and manipulate DNA. In addition, the laser can lead to the creation of super-fast computers and improved telecommunications.

Slide 3:

The team of researchers was led by Professor Xiang Zhang. He mentioned that the plasmon laser constricts light into a gap that is only 5nm wide. An important step was the ability to detain light in a small space for a specific period of time required for light to stabilize into a "coherent" laser state, having all of its waves synchronized. It is worth mentioning that plasmons are in fact wave-like movements of excited electrons on the surfaces of different metals. By connecting light to these oscillations, scientists managed to compress it further than usually, reports The Telegraph.

Tongue Drive system :

Tongue Drive system Scientists developed a new revolutionary system to help individuals with disabilities to control wheelchairs, computers and other devices simply by using their tongue.

Slide 5:

Engineers at the Georgia Institute of Technology say that a new technology called Tongue Drive system will be helpful to individuals with serious disabilities, such as those with severe spinal cord injuries and will allow them to lead more active and independent lives. Individuals using a tongue-based system should only be able to move their tongue, which is especially important if a person has paralyzed limbs. A tiny magnet, only a size of a grain of rice, is attached to an individual's tongue using implantation, piercing or adhesive. This technology allows a disabled person to use tongue when moving a computer mouse or a powered wheelchair .

Slide 6:

Scientists chose the tongue to control the system because unlike the feet and the hands, which are connected by brain through spinal cord, the tongue and the brain has a direct connection through cranial nerve. In case when a person has a severe spinal cord injure or other damage, the tongue will remain mobile to activate the system. The motions of the magnet attached to the tongue are spotted by a number of magnetic field sensors installed on a headset worn outside or an orthodontic brace inside the mouth. The signals coming from the sensors are wirelessly sent to a portable computer that placed on a wheelchair or attached to an individual's clothing.

Slide 7:

The Tongue Drive system is touch-free, wireless and non-invasive technology that needs no surgery for its operation. During the trials of the system, six able-bodied participants were trained to use tongue commands to control the computer mouse. The individuals repeated several motions left, right, up and down, single- and double-click to perform computer mouse tasks.

Slide 8:

During the trials of the system, six able-bodied participants were trained to use tongue commands to control the computer mouse. The individuals repeated several motions left, right, up and down, single- and double-click to perform computer mouse tasks. The results of the trials showed 100 percent of commands were accurate with the response time less than one second, which equals to an information transfer rate of approximately 150 bits per minute. Scientists also plan to test the ability of the system to operate by people with severe disabilities. The next step of the research is to develop software to connect the Tongue Drive system to great number of devices such as text generators, speech synthesizers and readers. Also the researchers plan to upgrade the system by introducing the standby mode to allow the individual to eat, sleep or talk, while prolonging the battery life.

SAMSUNG GALAXY TABLET:

SAMSUNG GALAXY TABLET Samsung Galaxy Tab is one of the contenders for being the best Android tablet out there. Credit goes to Samsung, for keeping it light in weight and unnecessary customizations. The moment we laid our eager, dirty hands on this tablet, we left smudges on its glossy back and screen. A bad start, but the tablet has a near perfect build besides this. It is light yet solid, thanks to the high grade plastic build.

Slide 10:

The onscreen keyboard is little better than the stock android keyboard, but presence of Swype in Android2.2 helps. Multi-touch and a good looking screen made it easy to love surfing on the device. The GPS navigation software is bundled by Google and works only in online mode, as it uses Google Maps service for maps. The battery life of the Tablet is decent, unless you are a heavy gamer, in which case the device also gets a little warm. Also, if you are on to use your USB port to charge your Gadgetry, you might as well stay away as the Galaxy Tab refuses to stuck any sort of power fed through USB port, charging about 10 pre cent in the three hours we plugged it in.

Slide 17:

Imagine arranging five ipads in the form of the cube (four sides and one top) and each of the ipad capable of communicating with the adjoining one and taken inputs from hand gestures. This concept was taken by the German based company Ident Technology AG. Each screen can interact with its adjoining screen and the user uses hand gestures to activate operation in the screen. This concept was showcased at the mobile world congress in Barcelona last year. The screens shows weather updates, send messages, play music and video and recognize devices like cell phones and wirelessly transfer data. GESTURE CUBE
